如何解决我如何将分页作为jsonify返回前端
这是我的管理图书清单，我想向其中添加分页。如何添加分页并以jsonify（）的形式返回到vue作为前端？
@phonebook.route('/admin/book/list')
@admin_authorize
def admin_books(user):
respone_body = dict()
respone_body['status'] = "success"
respone_body['code'] = 0
admin_book = admin_book(user.id,sort_by_id_desc=True)
respone_body['data']={
'books': admin_book,}
return jsonify(respone_body)
def admin_book(user_id,sort_by_id_desc=True):
admin_books = []
for book in Book.query.all():
admin_books.append({
"id": book.id,"name": book.name,"date": book.date,})
return sorted(admin_books,key=lambda dict: dict['id'],reverse=sort_by_id_desc)
感谢您的提前帮助！
解决方法
我得到了答案，这就是我在jsonify（）中返回Flask Restful Api分页的原因。MiguelGrinberg的Flask Book帮助我理解了这个概念
@phonebook.route('/admin/book/list')
@admin_authorize
def admin_books(user):
respone_body = dict()
respone_body['status'] = "success"
respone_body['code'] = 0
admin_book,pagination = admin_book(user.id,sort_by_id_desc=True)
respone_body['data']={
'books': admin_book,'page': pagination.page,'per_page': pagination.per_page,'total_page': pagination.pages,}
return jsonify(respone_body)
def admin_book(user_id,sort_by_id_desc=True):
admin_books = []
page = request.args.get('page',1,type=int)
per_page = current_app.config['PER_PAGE']
pagination = Book.query.paginate(page,per_page)
books = pagination.items
for book in books:
admin_books.append({
"id": book.id,"name": book.name,"date": book.date,})
return sorted(admin_books,key=lambda dict: dict['id'],reverse=sort_by_id_desc),pagination
我希望这会对以后以与我相同的方式做事的人有所帮助
